Auger effect

(ˈaʊɡə)
n
(Atomic Physics) the spontaneous emission of an electron instead of a photon by an excited ion as a result of a vacancy being filled in an inner electron shell
[C20: named after Pierre Auger (1899–1993), French physicist]

For atomic number 15 <Z < 30, the low energy structures associated with the K[[beta].sub.1,3] diagram line, can be interpreted in terms of KMM radiative Auger effect Radiative Auger Emission (14).
The diagram peaks are accompanied by a low energy band probably resulting from bonding states and possibly with a contribution of radiative Auger emission, which can be measured owing to the energy resolution and sensitivity of a WDS as illustrated by Takahashi et al.
This, combined with the lower probability of x-ray emission relative to competing Auger emission, means that EDX signal levels may decrease in intensity to the point where they are no longer measurable.
